Location is excellent, on the road, not hard to find, can walk to both train stations, but Hakata is a bit far, walk slowly to the room.
Service is a bit difficult when checking in by yourself, standing there confused for a while, but it's okay. The staff at Traveloka is good, can be contacted at all times, unlike some apps that are difficult to contact.
Room is excellent, clean and has complete amenities. It might be missing only an air purifier, but it's not a problem. The room is spacious (33 sq m.) with a lot of usable space.
Overall, I'm very satisfied with this accommodation. Everything is excellent.
I stayed during the season change. The room price is not expensive. But when I wanted to book the same place during the winter, the price went up, so I had to book somewhere else instead. If I have a chance, I will definitely come back to stay at SG again.
